HENRY L. BOOK, OF TOLEDO, OHIO,

ASSIGNOR, BY MESNE ASSIGNMENTS., TO THE BOCK COMPANY, A CORPORATION OF OHIO, (INCORPORATED IN OHIO IN MARCH, 1916.)

ROLLEEBEAEING.

To all whom t may concern Be it known that I, HENnY L. BooK, a citizen of the United States of America, 'residing at Toledo, in the county of Lucas and `State of Ohio, have invented certain new and useful flmprovements in Roller- Bearings, ication, reference being had therein tothe drawings.

The invention relates to roller bearings of the type in which radial loads arelcarried by cylindrical rollers and end thrust by enf largementsof said rollers forming contact- .in-g faces in alinement with the cylindrical faces.

Various constructions have been hereto-l fore devised in which enlargements have been formed integral with the .ltf'lrndrieal ortions of the rollers. With the present invention 'I have simplified the r'onstruction by employing balls 'for the `llargements formed separable from the cylindrical` rollbearings.

ers but arranged and retained in alinement therewith.

In the drawings: Figure 1 is a longitudinal section through a bearing constructed in accordance with my invention; Fig. 2 is a. crossseetion showing the construction of the cage or retainer; Fig. 3 is a side elevation thereof; and Figs. 4- and 5 are sections showing -a modified construction. l

A is a race member for engaging a series ofcylindrical rollers- 13.

(i and C are grooves formed 1n said race member at opposite ends oi the rollers B and providing bevel faces l) forming;r end thrust E fare balls of greater diameter' than the rollers B and arranged in axial alinement therewith, beine; held from displacement by engagement with 'recessesF inthe ends of the rollers. "if he halls E are ad aptedto bear against the end thrust bevel faces D at a point in alim-.ment with the cylindrical faces of the rollers, and` therefore the rollers andballs will travel aroundthe race member at the sal-'ne speed,- and without any differ- `enti al speedwviththe contacting faces of the raeemernber.

' Upon' the opposite 4side of the rollers and balls is a race member formed of separable sections, so as to permit assembly of the parts. This, "as shown, comprises a cylindrical member G for eontaotingvvith the c w lmdrical rollers and Vseparable members Specification of Letters Patent.

of 'which the following is a specl Patented Oct. 10, 1916.

Application mediana as, 1913. serial No. 176,273.

and Il sleeved Within the member G and providing opposed bevel faces I and I' for contacting with the balls E.

J is a cage or spacer, which is in the fornr of a ring interposedrbetwcen the inner and4 outer race members and provided with slots l( therein for receiving,r the cylindrical roll. ers, with enlargements L at their opposite ends for receiving the balls.

In assembling the parts, the cage J may be placed adjacent to the racc member A, and thc rollers B and balls E dropped into the slots K and L tllercrfround. Before placing the balls at one end in engagement `with the slots, the mcmberl is placed in position, and after said balls are engaged the Inelnl'iers ll and ll are sleeved upon the member (-l from opposite sides of the bear ing. Themen'ibers ll l l and (i are thuL held from disengamnnent by suitable clamping means-such as a nut M upon. ashaft N upon which said members are sleeved, and which Will clamp said members against a collar 0 on the shaft: y

lIn the modified construction shown in Figs. 4- and 5, in place of using separate balls, the rollers B are formed with enlarged spherical heads E integral there-y with, but are held in properly spaced` relation by a similar en,f,1;.l..,frement with a cage member .I. rl`his cage member' is4 formed with slots K and enlargements L to receive said rollers and preferably vwith the enlargements alternately upon opposite sides of the cage, aslshown. The parts may vbe assembler] in. a. sin'lila manner to that already described, andiw-hen in position Vthe bearing will. Icarry both radial and end thrust loads. f

vWhat I claim as my invention is: Y l

l. A roller bearing, comprising,r a seriesof vcylindrical rollers for .receiving Vradial thereof to receive end thrust and eoperating race members adapted to transmit radial and end thrust ,having contacting surfaces for said rollers and balls at equal distance from the axis thereof and from the axis of rotation to maintain the same peripheral speed.

3. A roller bearing, comprising a series of cylindrical rollers having concave ends, balls at opposite ends of each roller arranged in axial alinernent therewith, and coperatng race members having cylindrical bear ing portions and beveled end thrust portions having their bearing surfaces arranged in alinement with each other, the beveled end thrust portions having centrally located portions for contacting with the balls.

4. A roller bearing, comprising concentric race members, a series of rollers intermediate the same, enlargements at the ends of said rollers in axial alinement therewith, and an annular cage member interposed between said ra'ce members for substantially the entire length thereof, being spaced therefrom and rovided with slots for the passage'of said rollers and said enlargements therethrough.

5.*A roller bearing, comprising concentric race members, a series of rollers therei 1,2oo,45e

between, a series of balls arranged in axial ahnement with sald rollers and engaging lar cage interposed betweensaid race members and extending for substantially the entire length thereof, having slots for reoeiving said rollers and enlargements for re' ceiving said balls. y

G. A roller bearing, comprising a series of cylindrical rollers-for receiving radial thrust, balls for receiving end thrust arranged at lopposite ends of said rollers in axial alinement therewith, and race'members for engaging said rollers and lballs at points equidistant from the axis of rotation so as to maintain the same speed ratio, the portion of the race members for engaging the balls adapted to transmit end thrust anl having contacting surfaces extending syn' metrically upon opposite sides of the points" of contact.

In testimony whereof I affix my signature in presence o two witnesses.
